What is different about this stage

Dryness, pigment and loss of firmness tend to arrive together, and cleansing that worked for twenty years can start to feel stripping.

What sun damage & photoageing looks like here

The cumulative account — mottled tone, freckling, roughness and lines that track exactly where the sun reached.

Ingredients to lean on

🍊 Vitamin C🌾 Ferulic Acid🧫 Niacinamide (B3)🌙 Retinaldehyde (Retinal)🌻 Vitamin E (Tocopherol)
⚠️ Be careful with: Skipping SPF on cloudy days or indoors near windows
💡 Tip: Roughly the majority of visible facial ageing is attributed to sun exposure. A morning antioxidant plus reapplied SPF outperforms every night cream you could buy.
